Got an odd clearance the other day, on climbout from Santa Monica
(IFR but in perfect VMC): "climb and maintain 6000 when direct
Ventura". I took this to mean that someone would later clear
me direct VTU, whereupon I would climb. However I never got
such a clearance, and later an evidently nervous controller called
me, cleared me to 6000', and asked me if I had the terrain in
sight (which I did, but it was getting close for IFR though not
worrying visually).

I wonder what this clearance really meant? Did it mean "when ABLE
direct", i.e. when I could receive the VOR (which I couldn't
initially although I was filed /G anyway)? Or did someone just
forget to give me the subsequent clearance?
